Description

Technical Field

[0001] The utility model relates to the technical field of building roof decoration structures, and particularly relates to a waterproof and heat-insulating composite metal roof structure. Background Art

[0002] The roof structure is a structure arranged on the top or wall of the main body of a building, and the roof structure can play roles such as decorating the surface of the building, preventing rainwater scouring, and heat preservation. At present, the renovation, transformation, repair of buildings, the decoration of antique buildings, and the decoration of the roof and wall systems of cultural and tourism project buildings all require the use of roof structures. These practical scenarios have relatively high requirements for the waterproofing and heat preservation of the roof structure. The existing roof structures have limited waterproofing effects and require customized special conversion system accessories. When the waterproofing effect of the roof structure fails to meet the requirements, rainwater is likely to penetrate into the interior and surface of the roof structure, which may cause problems such as the aging of heat-insulating materials, the fading of building paint, and even building leakage. Therefore, in order to make the roof structure adapt to the requirements of building renovation, transformation, repair, the decoration of antique buildings, and the roof and wall systems of cultural and tourism project buildings, and to extend the service life of the roof system, a heat-insulating and waterproof composite metal roof structure with good waterproofing effects is needed.

Detailed Embodiments

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the drawings.

[0024] Please refer to Figure 1 and Figure 2 , a waterproof and thermal insulation composite metal roofing structure, including a roofing purlin 1, a decorative panel 4, a decorative bottom plate 2, a thermal insulation layer 5, and a standing seam roof panel 3.

[0025] The roof purlin 1 is fixed to the building wall or roof. The roof purlin 1 is a hollow round-corner rectangular steel pipe. The decorative bottom plate is fixed to the roof purlin 1, and a conversion purlin 23 and a thermal insulation layer 5 are provided on the decorative bottom plate. The conversion purlin 23 is fixed to the decorative bottom plate and is located directly above the roof purlin 1.

[0026] The standing-seam roof panel 3 is fixed to the conversion purlin 23 through a mounting seat. A standing edge 31 is provided on each of a set of opposite edges of the standing-seam roof panel 3. The two standing edges 31 of the standing-seam roof panel 3 are respectively a first standing edge and a second standing edge. Clamping grooves are provided on both the first standing edge and the second standing edge. The clamping groove on the second standing edge is clamped to the clamping groove on the first standing edge of the adjacent standing-seam roof panel 3. The decorative panel 4 is fixed to the standing-seam roof panel 3.

[0027] It can be understood that there are multiple decorative panels 4 and decorative bottom plates 2 in this application. The multiple decorative panels 4 and decorative bottom plates 2 are respectively spliced into an integral structure. The decorative panel 4 and the decorative bottom plate 2 are both weathering steel plates (weathering steel plates are steel plates resistant to atmospheric corrosion and belong to low-alloy high-strength structural steel plates). The decorative panel 4 and the decorative bottom plate 2 made of weathering steel plates will form a crystal-dense layer on the surface and are firmly combined with the base layer. This stable rust layer can, to a certain extent, block the intrusion of water vapor and harmful ions in the atmosphere, thereby greatly reducing the rusting rate of the weathering steel plates and extending the service life of the internal structures of the decorative panel 4 and the decorative bottom plate 2. Moreover, the surface of the weathering steel does not need to be painted, and there is no problem of paint aging, greatly reducing the maintenance cost. The decorative panel 4 and the decorative bottom plate are respectively located on the inner and outer sides of the main body of the roof structure, thereby comprehensively improving the aesthetics of the roof structure. A thermal insulation layer 5 is provided between the decorative panel 4 and the decorative bottom plate. The thermal insulation layer 5 can improve the thermal insulation characteristics of the roof structure. And there is a standing-seam roof panel 3 with edges that are mutually clamped between the thermal insulation layer 5 and the decorative panel 4. The first standing edge and the second standing edge at the edge of the standing-seam roof panel are mutually clamped and are 360° locked with each other through a seaming device. This structure can reach the first-class waterproof standard, which can greatly improve the waterproof performance of the roof structure, prevent rainwater from flowing into the thermal insulation layer 5, and extend the service life of the roof system.

[0028] Preferably, a vapor barrier film 51 is also attached to the decorative bottom plate and is located between the decorative bottom plate and the thermal insulation layer. A waterproof film 52 is also attached to the surface of the thermal insulation layer 5 away from the vapor barrier film 51. The vapor barrier film 51 and the waterproof film 52 can prevent the intrusion of moisture from the outside and steam from the inside into the thermal insulation layer 5, improve the service life of the thermal insulation layer 5, and improve the thermal insulation effect of the roof structure.

[0029] Preferably, the edge of the decorative bottom plate has a flanging portion 21 that bends upward. A support seat 22 is also provided on the decorative bottom plate. The two side edges of the support seat 22 are connecting portions, and the middle portion bulges upward to form a support portion. The connecting portions are fixed on the decorative bottom plate, and the support portion supports the conversion purlin 23. The upper surface of the support seat 22 is flush with the upper edge of the flanging portion 21, which facilitates the installation of the conversion purlin 23. The flanging portion 21 and the conversion purlin 23 can improve the structural strength of the roof structure.

[0030] Preferably, a plurality of keel strips 6 are further provided on the standing seam roof panel 3, and the decorative panel 4 is fixed to the keel strips 6. All the keel strips 6 are perpendicular to the roof purlin 1, and the keel strips 6 are used to support the decorative panel 4.

[0031] Preferably, refer to Figure 3 , a conversion support 7 is provided on the conversion purlin 23. The conversion support 7 includes a connecting plate, a support plate, and a support block 71. The connecting plate is connected to the conversion support 7, the support plate is vertically fixed on the connecting plate, and the support block 71 is fixed on the top of the support plate. The support block 71 supports the first standing edge of the standing seam roof panel 3, improving the installation strength of the standing seam roof panel 3. An insulation pad 72 is provided at the bottom of the connecting plate, and the insulation pad 72 is located between the connecting plate and the conversion support 7. The insulation pad 72 can improve the heat insulation effect of the roof structure and reduce the transfer of external heat to the interior.

[0032] Further, refer to Figure 4 , a buckle conversion member 8 is further provided between the keel strip 6 and the standing seam roof panel 3. The buckle conversion member 8 includes a conversion plate 81, a locking bolt 84, and two clamping plates 82. Clamping grooves 83 that are aligned with each other are provided on the inner sides of the clamping plates 82. The two clamping plates 82 clamp the buckling part of the first standing edge and the second standing edge through the tightening grooves, and the locking bolt 84 locks the two clamping plates 82. The buckle conversion member 8 is aligned with the conversion support 7, so that the load of the buckle conversion member 8 can be directly transmitted to the conversion purlin 23 and the roof purlin 1, thereby improving the overall structural strength of the roof structure.
